Target

The Target field of the CustomAction table contains an optional script function. Processing first sends the script for parsing and then calls the optional script function.

Return Processing Options

Include optional flag bits in the Type column of the CustomAction table to specify return processing options. For a description of the options and the values, see Custom Action Return Processing Options.

Execution Scheduling Options

Include optional flag bits in the Type column of the CustomAction table to specify execution scheduling options. These options control the multiple execution of custom actions. For a description of the options, see Custom Action Execution Scheduling Options.

In-Script Execution Options

Include optional flag bits in the Type column of the CustomAction table to specify an in-script execution option. These options copy the action code into the execution, rollback, or commit script. For a description of the options, see Custom Action In-Script Execution Options.

Return Values

Optional functions written in script must return one of the values described in Return Values of JScript and VBScript Custom Actions.

Remarks

A custom action that is written in JScript or VBScript requires the install Session object. The installer attaches the Session Object to the script with the name Session. Because the Session object may not exist during an installation rollback, a deferred custom action written in script must use one of the methods or properties of the Session object described in the section Obtaining Context Information for Deferred Execution Custom Actions to retrieve its context.
